oen-iuovnve DEVICE.

Application filed Novembergfi, 1926. Serial No. 151,562.

matically and alternately grip andrelease a car wheel during the operation of the device and cause the wheel torotateto impart movement to the car with' very little effort on the part of the operator.

'A further object of the invention is to provide a car moving device which includes means to prevent reti ograde movement thereof during its operation, thereby maximum force will be applied to the wheel of i the car with minimum effect upon the operator. m a

Another object of the invention is to provide apinch .bar of a rolling type that is strong and sturdy, easy to handle and will perform its intended function of placing and replacing cars without the diiliculty commonly attendant upon the use ,ofan ordinary pinch bar. 1

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, il-

lustrated in the accompanying drawings and specifically pointed out in the appended claims. c A

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which: i Figure l is a fragmentary side elevation showing my car moving device in operative position and applied to a wheel.

Referring to the drawings in detail the letter A indicates a car wheel ofthe usual flanged construction and B the track therefor 'My car mover which as previously set forth is in the nature of apinch bar and includes a roller carrying base formed by plates 1 secured'inparallelism to the lower end and upon opposite sides ofan upright housing or cylinder 2 and said plates are formed with bearings 3 to'recelve bolts 4;

which provide axles for rollers 5 having rail engaging flanges 6,118 best shown in Figure These rollers 5 have formed on their outer faces and flanges respect vely ratchet teeth 7 which have paWls S cooperating therewith. The pawls 8 are normally held in engagement with the teeth 7 by coil springs 9 surrounding bolts 10 which secure the pawls for lateral movement, to flanges 11 formed on the outer edge of substantially semi-circular members 12 which are arranged in spaced relation to the rollers 5 and secured to the plates 1 by bolts 13 as shown in Figure 3 of the drawings. The pawls are tapered from their securing points and pass through slots formed in the members 12 to prevent pivotal movement thereof, and their lower 1 ends are arranged for cooperation with the teeth 7 as above set forth so as to prevent retrograde or rear movement of the car moving device, but in no way hinder the forward movement thereof.

The upper portion of the housing or cyl inderQ is curved slightly'forward as at 14, and mounted for reciprocation 1n'th1s curved portion 14: is what 1 term a plunger includ ing a base 15 having its ends formed to fol-- in therear wall ofthe housing 2 and which is pivoted between cars extending from the housing as best shown in Figure 1 of the drawings. Rising fro m the base 15 is a sleeve 20 which as shown is ofrectangular formation and is provided with a bifurcated upper portion 21" having-parallelslots22 formed therein; Surrounding the sleeve 20f is a coil spring 23 having its end convolutionsengaging the base 15 and aninturned flange 24 formed on the-upper edge of the housing 2 and this spring 23 tends to urge the plunger 7 in its lowermost position'fas' shown in Figures 2 and 3 of the drawing. Mounted for reciprocation in the sleeve 20, is a dog carrying block 25 having depending therefrom a threaded stem 26 which'passes through an opening formed in the base 15 and is provided with a nut 27 to limit the upward movement of the block as will be apparent. The block has integrally formed or otherwise secured to opposite sides thereof a pair of apertured ears 28 which receive a pivot pin 29 for securing together and between said ears cooperating wheel actuating dogs 30 and 31. These dogs are of right angle formation as best shown in Figure 4 and have their securing shanks passing through the slots 22. Formed on their outer confronting faces are substantially V-shaped in cross section jaws 32 serrated to provide a positive gripping engagement with the wheels of a car. A coil spring surrounds 'the stem 26 and normally urges the block upwardly to cause the dogs to en; ;age the.

upper surface of the slots 22 and normally assume the position as shown in Figure 3 of the drawings.

The sleeve 20 has interiorly formed therewith a shoulder 34: which limits the downward movement of the block 25.

A carrying handle 35 is secured to and extends rearwardly from the curved portion 14, as clearly shown in Figures 1 and 2 of the drawings.

From the above description and disclosure in the drawings, it will be obvious that I have provided a car moving device which will readily place and replace cars as desired, with very little elfort on the part of the operator and the operation thereof may be described as follows: Assuming that the dogs 30 and 31 are in their normal position as shown in Figure 3, a slight upward movement of the handle 18 will cause the plunger to move downwardly and this movement will arrange the dogs in a true horizontal plane and whereby they can be caused to straddle the wheel A as best shown in Figure 1, then a downward movement of the handle 18 will cause the dogs to grip the wheel and impart movement thereto as will be readily apparent. By curving the upper portion of the housing or cylinder 2 as shown at 1%, it will be seen that the dogs can follow the wheel an appreciable distance before they are disengaged therefrom to repeat the gripping action as set forth. The ratchet rollers which cooperate with the pawls 8 prevent rearward movement of the device as previously outlined, and therefore the device will act with maximum force upon the wheel.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that/I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

hat I claim is:

1. A car moving device of the character described comprising a roller carrying base, a housing rising from said base and being provided with a curved upper portion, a plunger mounted for reciprocation in said housing, wheel gripping dogs carried by said plunger and means for operating said wheel gripping dogs for causing the latter to rotate a wheel of a car.

2. A car moving device of the character described comprising a roller carrying base, a housing rising from said base and provided with a curved upper portion, a plunger mounted for reciprocation in said housing, a sleeve included in said plunger, a block mounted for reciprocation in said sleeve, resilient means for limiting the downward movement of said block, wheel engaging dogs carried by said block and means for moving said plunger for causing the dogs to grip a wheel and cause rotation of the latter.

3. A car moving device of the character described comprising a roller carrying base, a housing rising from said base and being provided with a curved upper portion, a plunger mounted for reciprocation in the curved upper portion, ears depending from said plunger, a handle for moving said plunger and having connection with said ears, a sleeve included in said plunger, a coil spring surrounding said sleeve, resilient means for normally urging said. plunger to its lowermost position, means carried by said plunger and mounted for reciprocation therein, dogs pivotally secured to said means, wheel engaging jaws formed on said dogs and 111621115 to prevent movement ol said device in one direction. 4. A car moving device of the character described comprising a roller carrying base, means carried by said base to prcvent inovcment of the rollers thereof in one direction, a housing rising from said base, a plunger mounted for reciprocation in said housing, a sleeve included in said plunger, resilient means for urging said plunger in a clownward direction, a'block mounted for recipro cation in said sleeve, apertured ears forme on said block, dogs pivotally secured between said ears, jaws formed on the confronting faces of said dogs for engaging a car wheel and a handle for operating said plunger against the tension of the spring and to cause the dogs to alternately engage and release the wheel.

In testimony whereof I atiix my signature.
